Leaf Question

Hey people.....two questions??? This bending at the tips of the leaves, is this a ph issue? also.....is the serrated part of the leaf curling up a heat issue? Thanks everyone.

What are your temps?
PH?
PPM?
More info.

The curling up is a sign of heat stress. The bending I'm not sure of, but I don't think that's from ph.
